CLAMP FOR WASHBOWLS, 86C.

SPEGIFICAT'LQP .lng part of Letters Patent N o. 696,422, dated April 1,1902. Application led December 26, 1899. Serial No. 741,584. (No model.)

To @ZZ whoml it may concern.-

Be it known that I, EDWARD S. DUFFY, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Clamps for Washbowls,dac. of which the following is a specification.

This invention relates to clamps for washbowls, and has for its objectto provide a construction whereby a washbowl may be readily and firmlysecured to the stone slab which forms the top of the washstand.

To this end my invention consists in certain novel features, which Iwill now proceed to describe and will then particularly point out in theclaims.

In the accompanying drawings, Figure 1 represents a sectional Viewthrough a portion of a washbowl and its supporting-slab, the connectingdevice beingr showy., in elevation. Fig. 2 is a plan view et" theconnecting device detached. Fig. 3 is a sectional view taken on the line3 3 of Fig. 1 and looking in the direction of the arrow. Fig. 4 is aview similar to Fig. 1, illustrating a slightly-modified form of theconstruction therein shown. Fig. 5 is a View similar t0 Fig. |l,illustrating -a further modification of the device. Fig. 6 is a planview of the connectingdevice shown in Fig. 5. Fig. 7 is a transversesectional view taken on the line 7 7 of Fig. 5 and looking in thedirection of the arrow; and Fig. 8 is a view similar to Fig. 5,illustrating the mode of forming the split thimble in the last-mentionedmodification.

. Referring first to the construction shown in Figs. 1, 2, and 3 of thedrawings, 1 indicates the washbowl, which is provided with the usualoutward1yextending flange 2, and 3 indicates the stone slab which formsthe top of the washstand. Within this slab there is formed fromunderneath a cylindrical recess 4, within which ts a thi noble 5. whichis preferably corrugated exteinally in order to cause its outer surfaceto more firmly grip the wall 0f the recess 4. This thimble is split ordivided vertically, as indicated at 6, the two parts of the thimblebeing, however, integrally connected by means of a shank 7, extending atright angles to the thimble, from the lower portion thereof, so as tobear against the under side of the slab, the slit G extending somedistance along this shank. The slit 6 does not extend entirely to thebase of the thimble 5, but extends laterally to the periphery of thethimble some little distance above the base, as indicated at 7, and theunsplit or integral bas'e thus formed is provided with a threadedaperture 9. The body of the thimble above this base is provided with atapering aperture 10. 11 indicates Aa screw which fits the threadedaperture 9 in the base of the thimble and is provided with a tapering orconical head 12 which operatiA as a wed ge to spread the split body ofthe thimble. The lower end of the screw 11 is provided with the usualnotch 13, by means of which it may be turned. 14 indicates theclamping-arm, which in this construction is made integral with theshank' 7 of the thimble, bein g connected therewith by a bowed or springportion 15. This clamping-arm is provided with a slot 16, through whichthe screw 11 passes, and there is mounted on said screw below theclampingarm a nut 17. The device thusconstructed is utilized by placingthe thimble 5 within the cylindrical aperture 4 and at the same timeengaging the end of the clamping-arm 14 underneath the flange 2 of thebowl 1 after this latter has been brought into position under the slab3. The screw l1 may then be rotated in such a manner as to draw itsconical head 12 downward, so as to spread the two sections of thevertically-split upper portion of the thimble laterally outward andcause them to firmly clamp the device in po sition in the recess 4 ofthe slab 3. The nut 17 may then be screwed up upon the screw l1 in sucha manner as to press the free end of the clamping-arm 14 firmly againstthe flange of the bowl, and thereby hold the bowl in position againstthe under side of the slab. It will be observed that I obviate thenecessity of undercutting the recess 4 in the slab and do away with thecalking of the thimble in place by melted lead or other similar' means.The device may be readily and l quickly applied at a minimum of expenseand may when necessary be as readily removed. In Fig. 4 of the drawingsI have shown a modification of the construction just doscribed in whichthe integral connection between the clamping-arm 14 and the shank 7 ofthe thimble is dispensed with. In this construction I prefer tosubstitute for the slot 16 in the clamping-arm a threaded aperture 18,in which the screw 13 lits. I may, if desired, extend that end of theclampingarm which is not in engagement with the bowl-flange so that itwill rest upon the under side of the slab 3, as indicated in dottedlines at 19.

In Figs. 5, 6, 7, and 8 I have shown a further modication of the devicein which the thimble 5 is split vertically throughout its entire height,the slit 6 extending Gram top to bottom thereof, as shown in Fig. 8. Thetwo halves are, however, still integrally connected by means of theshank 7. The lower portion of the thimble is provided with a tapering orthreaded aperture 20, and the upper end of the screw 11 iscorrespondingly tapered and threaded, as indicated at 21. I have alsoshown the thimble as provided with a smooth exterior and surrounded by asplit jacket 22, of lead or other soft metal. It will be obvious thatrotation of the screw 11 will force its tapered extremity into thecorrespondingly-tapered aperture in the thimble and will spread thislatter, so as to force the lead jacket rmly'against the walls of therecess 4, and thereby firmly connect the device to the slab 3. Thestructure is in other respects similar to that already described inconnection with Figs. 1, 2, and 3 of the drawings.

Various other modifications will readily suggest themselves, and I donot wish to be understood as limiting myself to the precise detailshereinbeiore described, and shown in the drawings.

1. The combination, with a slab having a cylindrical recess, and a bowl,of a clamping device comprising alongitudinally-split thimble and aclamping-arm integrally connected therewith, a screw threaded to engagethe thimble and having a conical or tapering portion to spread the same,and a nut mounted on said screw and bearing against the clamping-arm,substantially as described.

2. The combination, with a slab having a cylindrical recess, and a bowl,of a clamping device comprising a thimble of uniform external diameteradapted to iit the recess and split both` longitudinally andtransversely,the lower portion being threaded, a screw adapted to t saidthreaded portion and having a conical or tapering portion to spread theupper or vertically-split portion of the thimblc, a clamping-arm toengage the bowl, and a nut mounted on the screw and bearing against theclamping-arm, substantially as described.

3. The combination, with a slab having a cylindrical recess, and a bowl,of a clamping device comprising a thimble adapted to t the recess andsplit both vertically and horizontally, the lower portion beingthreaded, a clamping-arm adapted to engage the bowl and integrallyconnected with the thimble, a screw engaging the threaded portion of thethimble and .having a tapering or conical portion to spread the thimble,and a nut mounted on said screw and bearing against the clampingarm,said arm being apertured or slotted for the free passage of the screw,substantially as described.
